What are the symptoms of chronic renal failure

What are the symptoms of chronic renal failure? Chronic renal failure is a very serious kidney disease , the prevalence of injury to the patient's body is great, and therefore we must draw attention to the chronic renal failure , if an illness in a timely manner to regular hospital checks , in accordance with the clinical course of conduct after diagnosis for treatment , then the next I will introduce what are the symptoms of chronic renal failure .
What are the symptoms of chronic renal failure, chronic renal failure, duration of clinical symptoms? :
1 , pre- uremic
Renal failure glomerular filtration rate is reduced to 10-15 ml per minute, the nephron reduction of approximately 70% -90 %, severely impaired renal function, metabolism in the body canbe argued, and water and electrolyte and acid-base balance. Impossible to keep a stable internal environment, resulting in serum creatinine, blood urea nitrogen increased significantly, diluted urine concentration dysfunction, acidosis, sodium retention, low calcium, high phosphorus, potassium and other balance disorders performance. May has significant anemia and gastrointestinal symptoms such as nausea, vomiting, loss of appetite. May be necessary neuropsychiatric symptoms, such as fatigue, lack of concentration, lack of energy and so on.
2 , azotemia
Reduction of azotemia glomerular filtration rate to 25 ml / min, being reduced by 50% -70 % of renal units, renal dysfunction concentrated, there nocturia or urine, varying degrees of anemia, azotemia often, serum creatinine, blood urea nitrogen levels. Clinically fatigue, loss of appetite, mild nausea and general discomfort.
3 , renal decompensation
Uncompensated renal function, reduce GFR to 30-60 ml / min, and normal glomerular filtration rate of 120 liters per minute. A decrease of approximately 20% -25 % of renal units in this period. Despite the loss of renal reserve capacity, but for the excretion of metabolites, regulation of water, electrolyte and acid-base balance is always good, there are no specific clinical manifestations, serum muscle enzymes are usually normal blood urea nitrogen, or sometimes mildly elevated.
4 , uremia
Glomerular filtration rate decreased to , 10 ml -15 ml per minute or less , more than 90% reduction in renal units , this period is late chronic renal failure, renal failure symptoms above more obvious manifestations of systemic multi- organ failure , such as gastrointestinal , neurological , cardiovascular , hematopoietic system, respiratory system , skin and metabolic system imbalance .

These are the symptoms of chronic renal failure for which related presentations made ​​, I like to be helpful to remind everyone in life can develop good habits. If the body once abnormalities, should take the lead in a regular hospital for treatment.
